TRIMMER EOR BATTERY SEPABATORS Application fiieaA st 1, 19211. se mrn458, 32,,

To allwhom it may concern Be it. known that. I, JOHN E. NoRR s, acitizen of the. United States, residing at Indianapolis, in the. countyof Marion and State. of Indiana, have, invented certain new and, usefulImprovements, in 'Irirhrhers v fer V .attery Separators, of which thefollowing is a specification. 1

This invention relates. to. trimmers, and .is designed primarily fortrimminggbattery separators, and-theprime. feature of theginvention isthe provision of cuttingelements, which arespaced; a uniform distanceapart and; adapted. for trimming opposed. edges of a plurality.ofseparators, for redueingthe separators to uniform size. T

A furtherv feature of the inventionis. the provision of means. forimparting a reciproeating. movement to the cutting. elements, so thatasubstantially shaving effect will be. imparted. to. the cutting.elements.

A further feature of; the invention is the provision of means forholding a plurality of the separatorsin compact formation during thetrimming operation, andv a further feature of: theinvention istheprovision of means, for gradually feeding the separators towards. thecuttingelements. i 1

Other. objects and advantages will. be hereinafter more fullyset forthand pointed out in the accompanying specification.

In the accompanying drawings which, are made a part. ofthis.application,x

complish this result a...pair ..of.clarnping member$ lgiand 19..aremounteduponfla cairri selgqz were"ease -e e slide l mounted on the bedplate 1, the clamping member 18 being fixed to the carriage 20, whileclamping member 19 is movably mounted thereon.

The separators 17, after being bunched together, are positioned betweenthe clamping members 18 and 19, an adjustable gulde bar 21 beingattached to the bed determining the position of one edge of theseparators. The separators are then forced into close proximity, and areheld in fined position by operating a feed screw 22, which is threadedthrough a bearing 23 on the outer end of the carriage 20, the inner endof the feed screw engaging with clamping member 19, while the outer endthereof 1s provided with a hand wheel 241 for conveniently operating thefeed screw.

The carriage 20 is preferably provided with a dovetail tongue 25, whichenters a dovetail groove 26 in the bed plate 1, the carriage being heldin proper ahgnment by means of an adjustable bar 27 said baralso servingto take up any wear on the carriage.

After the separators have been properly clamped between the clampingmembers 18 and 19, they are fed towards the cutting elements 13, bymoving the carriage lengthwise. Although this result may be accomplishedin many different ways, in this nstance a toothed rack 28 is connected wth the carriage 20, which rack co-operates with a gear 29, mounted upona shaft 30, one end of the shaft having a power applying wheel 31connected therewith, which in this instance is shown as hand operated.

In order to impart a substantially shaving action to the cuttingelements as they are severing the edges of the separators, the cuttingelements are reciprocated vertically through the medium of eccentrics32, which are mounted upon a driven shaft 33, the eccentric rods 34being connected with a cross bar 35, which is in turn connected to theupper edge of the frame 5; consequently when the shaft 33 is rotated theframe 5 and parts carried thereby will be moved back and forth in avertical plane, thus causing the cutting plates to more readily severthe edges of the separators.

In operating the device the feed screw 22 is turned to move the clamping.member 19 V away from the clamping member 18, when a bunch or stack ofseparators is introduced between the two clamping members 18 and 19, andone edge thereof forced against the guide bar 21. The feed screw 22 isthen operated in the opposite direction, thus securely clamping thebunch of separators in position on the carriage 20.

, Power is then applied to the shaft 33 through the medium of a beltpulley 36, or

"otherwise, the rotation of the shaft 33 causing the plates 13 toreciprocate vertically. Power is then applied to the shaft 30,

plate 1, for p curing together through the medium of the hand wheel 31,or otherwise, the gear 29 engaging with the rack 28 moving the carriage20 and the bunch of separators thereon into engagement with the cuttingedges of the plates 13, the plates readily severing the edges of theseparators, and as the plates are spaced a uniform distance apart, theseparators will be trimmed to a uniform size, and after the side edgesof the separators have been trimmed the bunch may be given a half turnby loosening the clamping member 19, so that the opposite or end edgesof the separators may be trimmed as effectively across the grain, aswith the grain. It will likewise be seen that although the device isshown and described as used for trimming battery separators, it may beused for trimming various other articles.

Having thus fully described my said invention, what I claim as new anddesire to secure by Letters Patent, is:

1. In a trimming device, means for sea plurality of separators, cuttingelements for trimming the edges of the separators, means for advancingthe separators towards the cutting elements, and means for impartingvertical movement to the cutting elements whereby the entire group ofseparators is brought into contact with the cutting elements at a singleadvancement of the separators, substantially as set forth.

2. In a trimming device, means for clamping together a plurality ofseparators, a pair of spaced cutting elements, means for impartingvertical reciprocating movement to the cutting elements, and means forfeeding the separators horizontally towards the cutting elements.

3. In a trimming device, vertically disposed cutting elements, means foradjustably spacing the cutting elements with re spect to each other, avertically movable frame for carrying the cutting elements, means forimparting reciprocating vertical movement to said frame, clampingmembers for holding a plurality of elements to be trimmed in compactformation, and means for moving the elements to be trimmed intoengagement with the cutting elements.

4. In a trimming device, a group of separators, means to advance theseparators horizontally, a pair of oppositely spaced cutting elements,means for reciprocating the cutting elements vertically, means foradjusting the cutting elements by varying the distance therebetween andother means for adjusting the cutting elements in the directionof themovement of the separators,

, substantially as set forth.

edges, a pair of knives arranged to contact with the said verticallyopposed edges of the separators, means for horizontally reciprocatingthe group of separators, and means for vertically reciprocating theknives, substantially as set forth.

6. In a trimming device, a group of separators, said separatorspresenting vertically opposed edges and horizontally opposed edges, apair of knives arranged to contact With the said vertically opposededges of the separators, means for horizontally reciproeating the groupof separators, and means for bringing into contact with the said knives,the said horizontally opposed edges 15 of the separators, substantiallyas set forth. In Witness whereof, I have hereunto set my hand and sealat Indianapolis, Indiana, this 27th day of July, A. D., nineteen hundredand twenty-one.
